Part 1: This week, you will attempt to estimate (guess) how much you spend each month on everything. This information won't be shared with the course community, only with the instructors.
This means rent or mortgage, gym memberships, insurance, day care, etc. Try to list every possible expense.
Use the attached document or create your own to estimate how much you spend each month on EVERYTHING.
Part 2: Determine a method you plan to use to track your spending (if you aren't already). This can be pen and paper, a spreadsheet you keep on your computer, or actually using your credit card statements. Consider using a free app or an automated system like mint.com.
